Newborn Jaundice in Indian Babies: Causes, Signs and Treatment

• Most newborn jaundice is physiological, harmless, and clears on its own by day 7 to 14 with continued feeding and observation.
• Jaundice in the first 24 hours of life, or yellowing that reaches the palms and soles, is always an emergency, no matter how mild it looks.
• Behaviour matters as much as colour: lethargy, poor feeding, a weak suck, or a high-pitched cry needs same-day paediatric review.
• Never stop breastfeeding because of jaundice. More frequent feeding, not formula, is the right management for almost all healthy term babies.
• Putting a baby in direct sunlight is unsafe and does not work. Medical phototherapy uses a specific, controlled blue light and is the safe treatment.
• G6PD deficiency, ABO and Rh incompatibility, and prematurity raise the risk of pathological jaundice in Indian newborns and deserve early flagging to the paediatrician.

Newborn jaundice is the yellow tinge of the skin and the whites of the eyes (the sclera) caused by a rise in bilirubin, a yellow pigment made when red blood cells are broken down. Newborns produce bilirubin two to three times faster than adults because they are born with extra red blood cells that need to be turned over after birth. At the same time, the liver enzyme that processes bilirubin (UGT1A1) is still maturing in the first week. The result is a temporary mismatch between how much bilirubin is made and how fast it is cleared, so it builds up in the skin and gives the characteristic yellow colour.

The yellowness usually appears first on the face, then moves down the body as bilirubin rises, reaching the palms and soles only at the highest levels. Most cases are mild and physiological: bilirubin peaks around day three to five and settles by day seven to ten in term babies, sometimes a little longer in preterm or breastfed babies, and causes no harm. A smaller share is pathological and needs prompt evaluation. If you are still getting your bearings with how the first few days unfold, our guide to what happens after delivery sets the scene.

Physiological jaundice is the normal, mild jaundice of healthy term newborns. It appears from day two onwards, peaks around day three to five (usually below 15 mg/dL), and clears by day seven to ten without treatment. The baby is otherwise well: feeding actively, passing urine and stool normally, alert when awake, and starting to regain weight after the usual early dip. The yellow is limited to the face and chest. Nothing is needed beyond frequent breastfeeding (eight to twelve feeds in 24 hours), daily observation, and the standard follow-up visits. A normal early weight dip is expected, and our guide to newborn weight loss and gain tracking explains the safe range.

Pathological jaundice is different and needs prompt medical attention. The warning features are jaundice that appears in the first 24 hours of life (almost always pathological and an emergency), a rapid rise of more than 5 mg/dL per day, a level above the treatment threshold for the baby's age and gestation, persistence beyond 14 days in term babies (or 21 days if preterm), yellowing that reaches the palms and soles, or jaundice with lethargy, poor feeding, pale stools, or dark urine. Common causes include G6PD deficiency, ABO or Rh incompatibility, infection (sepsis), cephalohaematoma, prematurity, and rarely a liver or metabolic problem. This group almost always needs hospital evaluation, bilirubin testing, and often phototherapy.

A few risk factors are worth naming specifically for Indian newborns. G6PD (glucose-6-phosphate dehydrogenase) deficiency is the most important. It is an inherited, X-linked enzyme deficiency that makes red blood cells more fragile, affecting roughly 8 to 9 percent of Indian newborns overall and more in some communities (Kashmiri, Sindhi, Konkani, Parsi, and certain tribal populations). G6PD-deficient babies can develop severe jaundice quickly, especially after exposure to triggers such as naphthalene mothballs (common in Indian wardrobes), certain drugs, fava beans, and some traditional herbal remedies. Many states now offer G6PD screening as part of the newborn heel-prick screening test, and any family history of jaundice or G6PD should always be mentioned to the paediatrician.

ABO incompatibility (mother O group, baby A or B) and Rh incompatibility (mother Rh-negative, baby Rh-positive) cause haemolytic jaundice that often appears in the first 24 hours and rises fast. If you are Rh-negative, our guide to Rh-negative pregnancy and anti-D explains how this is prevented and monitored. Infection (sepsis) is a major cause of pathological jaundice, particularly with risk factors like prolonged rupture of membranes or maternal fever, and any jaundice with lethargy, poor feeding, or temperature instability needs an urgent sepsis check. A cephalohaematoma (a collection of blood under the scalp from delivery) adds bilirubin load as it resorbs.

Gestation matters too. Late-preterm babies (35 to 36 weeks) and early-term babies (37 weeks) have less mature liver enzymes and higher jaundice risk than babies born at 40 weeks, and India's higher rate of preterm and late-preterm birth adds to the burden. If your baby arrived early, our guides to premature birth and NICU care and to late-preterm babies born at 35 weeks cover what to expect.

The Kramer scale is a simple visual tool that lets parents and ASHA workers estimate jaundice severity by how far down the body the yellow has spread. Because jaundice always starts at the face and moves downward as bilirubin rises, the lower the yellow reaches, the higher the level. Zone one is the face and neck (roughly 4 to 8 mg/dL), zone two extends to the upper trunk above the navel (8 to 10), zone three covers the lower trunk and thighs (10 to 12), zone four reaches the arms and legs below the knees (12 to 15), and zone five is yellowing of the palms and soles (above 15 mg/dL, almost always needing phototherapy).

Check in natural daylight, never under yellow indoor lighting, which masks the colour. Undress the baby enough to see the area, gently press a finger on the skin over a bony spot such as the forehead, nose, or chest, then release. The blanched skin reveals the true underlying colour. Check once a day at the same time, ideally in mid-morning light, and note how far the yellow has progressed. Yellowing of the palms and soles is the single most important warning sign and means you should contact the paediatrician the same day. Remember that the Kramer scale is a screening aid only; it does not replace a bilirubin test when treatment decisions are being made.

Some signs of jaundice need urgent, same-day, or emergency evaluation because they point to pathological jaundice and a risk of kernicterus (bilirubin brain injury, which is rare but devastating and largely preventable). Jaundice appearing in the first 24 hours of life is almost always pathological and is an emergency: contact the paediatrician or a hospital with a NICU immediately, no matter how mild the yellow looks. Yellowing that reaches the palms and soles signals very high bilirubin and needs urgent assessment for phototherapy.

Behavioural red flags matter just as much and can appear before the colour looks alarming. Go for immediate review if your baby is unusually drowsy and hard to wake for feeds, feeds poorly or refuses feeds, has a weak suck or a high-pitched abnormal cry, arches the back or has stiff or floppy muscle tone, has fewer than six wet nappies in 24 hours after day three, develops a fever or unstable temperature, or whose yellow worsens fast over 12 to 24 hours. Fever in particular is never to be brushed off; see our guide on when a baby's fever needs the doctor. These can be early signs of bilirubin affecting the brain, and the window to prevent harm closes quickly.

Other red flags include pale, white, or chalky stools and dark urine, which suggest a liver or bile-duct problem and are never normal in a newborn; jaundice lasting beyond 14 days in a term baby (or 21 days if preterm); and any jaundice in a baby with known risk factors such as G6PD deficiency, ABO or Rh incompatibility, prematurity, infection risk, or a cephalohaematoma. Pale stools deserve special attention, and our guide to white baby poop and what it can signal explains why. In any of these situations, do not wait and watch; go directly to a hospital with a NICU.

Two tests measure bilirubin in newborns, and both are widely available in India. Total serum bilirubin (TSB) is the reference test, done on a small blood sample from the heel or a vein, processed at any hospital or pathology lab. It costs roughly 150 to 400 rupees in private labs and is free in government hospitals. TSB gives an exact number that can be plotted on the Bhutani nomogram, an age-in-hours chart that defines the phototherapy and exchange-transfusion thresholds for each baby's gestation and risk profile.

Transcutaneous bilirubin (TcB) is a non-invasive reading taken with a small handheld device pressed to the baby's forehead or chest. It gives an instant result with no blood draw and is offered free at most government hospitals and many private NICUs as part of newborn screening. TcB tracks TSB well at lower levels (below about 15 mg/dL) and is a good screening tool, but a TSB blood test is still done to confirm before starting phototherapy or making major decisions. The Bhutani nomogram is the standard interpretation tool recommended by the Indian Academy of Paediatrics: the same bilirubin number means very different things at 24 hours of life versus 72 hours, and the chart makes that clear.

Phototherapy is the standard treatment when bilirubin crosses the Bhutani nomogram threshold. It uses a specific wavelength of blue light (around 460 nanometres) to convert bilirubin in the skin into water-soluble forms the baby can pass out in urine and stool. In hospital, it is given in the NICU or postnatal ward using overhead LED units, with the baby undressed except for a nappy and eye protection, and turned regularly so the light reaches the whole body. Hospital phototherapy is free in government facilities (district hospitals, medical colleges, and many CHCs have units) and costs roughly 1,000 to 3,000 rupees a day in private hospitals, including the bed charge. Government schemes such as PMJAY can cover NICU care for eligible families.

Home phototherapy is increasingly available in Indian cities for mild to moderate cases where the baby is otherwise well and the family can manage daily monitoring. LED units can be rented for roughly 200 to 500 rupees a day from medical-equipment companies and some hospital tie-ups, delivered to the home and used under the paediatrician's remote supervision with daily bilirubin checks. It is suitable only when the paediatrician specifically recommends it and the level is in the lower-treatment range. Severe jaundice, any red flag, or any baby with risk factors needs hospital admission. Exchange transfusion, which replaces the baby's blood with donor blood, is the rare third-line treatment for severe jaundice that does not respond to intensive phototherapy and is done only in tertiary NICUs.

Throughout phototherapy, feeding continues. The baby is taken out for feeds every two to three hours and returned to the light afterwards, which keeps milk intake up and helps the body clear bilirubin faster.

Two breastfeeding-related types of jaundice are often confused. Breastfeeding jaundice (also called suboptimal-intake jaundice) appears in the first week and is caused by not getting enough milk: a poor latch, infrequent feeds, or low early supply leads to mild dehydration, less bilirubin is cleared in the stool, and the level rises. The treatment is more breastfeeding, not less. Aim for ten to twelve feeds in 24 hours and fix latch problems early, ideally with a lactation consultant or trained nurse. Our latch troubleshooting guide and the basics of breast, bottle and combination feeding can help, and colostrum in these first days is far more valuable than its small volume suggests, as our colostrum guide explains. Add expressed milk or formula top-ups only if the paediatrician advises after weighing the baby.

Breast-milk jaundice is different. It appears later (from the end of the first week through several weeks), is caused by substances in breast milk that increase bilirubin reabsorption from the gut, and is a benign condition in an otherwise well baby. It does not need treatment, does not need stopping breastfeeding, and resolves on its own over several weeks while the baby feeds and grows well. The single most important message is this: never stop breastfeeding because of jaundice. The old advice to switch to formula for a few days is outdated and harmful. Continued frequent feeding (eight to twelve feeds in 24 hours) is the right management for almost all jaundice in healthy term babies. If you are pumping to keep supply up while managing all this, our breast milk storage and pumping guide covers the practicalities.

Once you are home, daily monitoring is straightforward and well within any parent's ability. Check the jaundice once a day at the same time in natural daylight using the Kramer method above, pressing gently on the forehead, nose, or chest to see the blanched colour, and note how far down the body it has spread. A photo taken in the same light each day is a useful way to compare and to share with the paediatrician if needed. Count nappies and stools: a well-hydrated breastfed baby should have at least six wet nappies in 24 hours after day three and three or more yellow, seedy stools a day. If the colour of those stools ever changes, our baby poop colour and consistency guide explains normal versus concerning.

Weigh the baby at the standard follow-up visits on days three, seven, and fourteen. Your ASHA worker provides this free under home-based newborn care in most states, or the paediatric clinic does it. A baby who has lost more than 10 percent of birth weight, or who has not regained birth weight by day 10 to 14, needs evaluation, usually of feeding adequacy. Watch behaviour too: a well baby is alert when awake, feeds actively for about 15 to 20 minutes per side every two to three hours, has good muscle tone, and cries normally. Any shift towards drowsiness, poor feeding, weak suck, high-pitched cry, fever, or fast-worsening yellow is an immediate reason to call the paediatrician.

The Indian Academy of Paediatrics (IAP) and the Ministry of Health and Family Welfare (MoHFW) recommend home-based newborn care visits by the ASHA worker on days 3, 7, 14, 21, 28, and 42 for normal-weight babies, with extra visits on days 2, 4, and 8 for low-birth-weight babies. These visits are free under the National Health Mission and cover weight, jaundice screening, feeding assessment, and danger-sign identification, making them one of India's most effective newborn-health interventions. The ASHA worker refers the baby to a paediatrician at the PHC, CHC, or government hospital if any concern is found.

Alongside the home visits, paediatrician follow-up is typically at the clinic on day 3 to 5 (often the first formal visit), day 7 to 10, day 14, and again at four to six weeks. Babies with risk factors, or any jaundice that needed treatment, have extra bilirubin checks until the level is clearly falling. If there is a family history of G6PD deficiency or unexplained severe jaundice in siblings, ask specifically for a G6PD test for the baby; it is not always routine and costs roughly 200 to 600 rupees in private labs, free in government hospitals.

Immunisation continues on the normal schedule even after jaundice. BCG, hepatitis B, and OPV at birth, and the six-week vaccines that follow, are not affected by past jaundice, and delaying them only raises the risk of vaccine-preventable infection. The paediatrician will confirm timing at each visit; for the full plan see our baby vaccination schedule for India.
